The public outrage expressed when Australian cricket players admitted to cheating during a Test match by using sandpaper alter the surface of ball was, for some observers, matched an incredulity captured in variants question, ‘how did they think could get away with it?’ Drawing upon insights from recent work within masculinity studies, this essay offers explanation into how overlook severity th...

Fibre metal laminates (FMLs) are lightweight structures with high structural performance and suitable for many industrial applications. This work describes the impact behaviour of novel sisal fibre-reinforced aluminium (SiRAL) their dependence upon orientations fibres, composite core used surface treatment skins. A cold-pressing technique is to produce SiRALs in six configurations. The FMLs her...

Media pembelajaran yang digunakan mengenalkan media Sandpaper Numerals dengan metode Montessori. Metode diawali meraba media, menyebutkan ...

in order to find the most effective method to overcome seed dormancy in teucrium chamaedrys  l. medicinal plant species the effect of some chemical and physical breaking methods including: cold stratification (5 °c), scarification with sandpaper, stratification with needle, concentrated sulfuric acid, gibberellic acid and combination of these methods were investigated. treated seeds along with ...

This study aims to determine the effect of concentration turmeric powder (Curcuma domestica Val.) as an abrasive and antioxidant on characteristics a body scrub cream adding produce best cream. used randomized block design with variations in six (0%, 2%, 4%, 6%, 8%, 10%). The treatments were grouped into 3 based time making so that 18 experimental units obtained. Data analyzed by analysis varia...

Superhydrophobic surfaces have received increasing attention due to their excellent water repellency, but the fragile stability of superhydrophobic coatings has been a huge hindrance applications. In this work, we constructed layer mullite fibers on surface ceramic substrate using high-temperature molten salt. Then, obtained with contact angle greater than 150° via soaking sample an alcoholic s...

In this study, experimental and numerical investigations were carried out to achieve a comprehensive understanding of the impact surface conditions on self-piercing riveting (SPR) joint quality. Oil lubrication sandpaper grinding employed in tests change at rivet/top sheet, top/bottom sheets bottom sheet/die interfaces. A finite element (FE) model for SPR process was also adopted numerically as...

The major cause of early failure in the infrastructures palm oil industry Aceh, Indonesia has been discovered to be corrosion caused by air pollution from exhaust fumes factory plants. Therefore, this research was conducted analyze effect atmospheric structural steel used mill industry. five types as samples include strip, l-shape, round bar, plate, and SAPH 610 low carbon with a content 0.18%....

Cooling in liquid nitrogen is a typical service condition of high-temperature superconducting wire, and the variation boiling stages on wire protective layers such as brass could be crucial for quench behavior devices. In this study, influence surface morphology (parameters roughness fractal dimension) Leidenfrost effect (including wall superheat at critical heat flux point, which are respectiv...

The flashover strength of epoxy (EP) insulations in the High voltage direct current applications future energy grids can be improved by tailoring their surface condition. This work aims to improve DC characteristics EP after being treated with sandpaper different gradings. Samples virgin and homogenously modified considering varying roughness (Ra = 0.54, 3.16, 5.24, 8.35 μm) are prepared. Diffe...
